摘 要:以3,3'-双[单硝甲基-ONN-氧化偶氮基]氧化偶氮呋咱为原料,经过硝化,二次硝化两步反应合成了3,3'-双[三硝甲基-ONN-氧化偶氮基]氧化偶氮呋咱(BTNAF),总收率为68.7%;首次利用示差扫描量热法(DSC)研究了BTNAF的热行为,其熔点为59~61℃,分解温度为183.6℃,放热量为1989J·g^(-1);通过高斯计算,对比了BNMAF,BDNAF和BTNAF的物化性能和爆轰性能,结果表明,BDNAF(爆速9560m·s^(-1),爆压42.40GPa)和BTNAF(爆速8944m·s-3,爆压38.48GPa)是潜在的性能突出的含能化合物。Abstract: Using 3,3'-bis( nitromethyl-ONN-azoxy)azoxyfurazan(BNMAF) as starting material, an excellent energetic compound 3,3'-bis(trinitrom- ethyI-ONN-azoxy) azoxyfurazan(BINAF) was synthesized via two steps ( nitration and second nitration)with a total yield ot 68.7%. The thermal behavior of BTNAF was investigated by differential scanning calorimetry(DSC) for the first time ( melting point: 59-61 ℃, decomposition point: 183.6℃, decomposition heat: 1989 J· g-1 ) The physicochemistry and detonation performances of 3,3'-his(nitromethyl-ONN-azoxy) azoxyfurazan (BNMAF), 3,3'-bis(dinitromethyI-ONN-azoxy) azoxyfurazan (BDNAF) and BTNAF were fully analyzed and compared by Gaussian, which revealed that BDNAF (detonation velocity: 9560 m· s-1 ; detonation pressure: 42.40 GPa)and BTNAF (detonation velocity: 8944 m· s-3; detona- tion pressure: 38.48 GPa)were two promising energetic compounds with outstanding performances.
